GANformer introduces a novel transformer architecture for image generation, replacing the standard adversarial loss stage with a multiplicative integration mechanism. It leverages a bipartite structure to facilitate long-range interactions across the image features while maintaining linear computational complexity. The network iteratively propagates information between latent variables and visual features, promoting compositional representations of objects and scenes. It offers a generalization of StyleGAN.
GANformer distinguishes itself through its bipartite structure enabling long-range interactions with linear computational cost, offering potential for scalability to high-resolution image synthesis. It utilizes multiplicative integration for flexible region-based modulation, a significant departure from conventional transformer architectures. The repository provides implementations in both TensorFlow and PyTorch, and supports various dataset resolutions up to 2048x2048. It also offers pre-trained models and comprehensive documentation.
